This is a follow- up on my in frame HF79/ alternator/ 450w Huffy. Went for a couple of rides today (40 degrees, sunny and wind).
Previously,I blew one 24v alt. regulator, maybe another, then the latest was a dud.
So I put the Ford alternator back in (instead of the Delco), fed the field circut from ONE of the batteries (giving 12v to the field only), set the max voltage out of the alternator at 30 via the handy throttle limit screw and went for a ride.
The engine is really at a fast idle to obtain thirty volts (I figure that number is safe with the controller and old batteries I'm using. Idling gives around 25, but drops big time when the elect. throttle is cranked. Thus the 30 setting.
The Delco did give more power but, without the needed regulator, I thought- nothing to loose puting the Ford in.
The bike handles nice, speed, between 15 and 20 I guess. Depending on wind and going up or down.
Pretty quiet.
The cool thing is, I get to where I want about 2x faster than the pedal only bike and am not a sweat ball upon arriving.
Still pedal a little to help the motor.
I wonder if I will ever use the nice Trek I got last year.
I also took power off one of the batteries for 12v lights, this is possible because of the twin battery set-up.
The alternator output is wired direct to the batteries 24v output and I put a big switch to shut off power to the controller. (Pic 2).
